First verify where the fan is hitting. There should be "witness" marks left on the inner shroud. Verify that the fan blades are equidistant from the shroud all the way around using one blade only and spinning the fan with the belt off. If not, the position of the marks will tell you which way...

By using a quality electric puller fan, a relay and one of these, you can have your fan stay on for up to 3 minutes after shutting the engine off: http://www.dakotadigital.com/index.cfm/page/ptype=product/product_id=852/category_id=403/mode=prod/prd852.htm I use these on both my classics and...

The very first thing you need to do is to ensure that your actually getting the right temperature reading from your gauge. Wouldn't be the first time that a temperature gauge was wrong. If you're using an aftermarket gauge be sure the sensor is in the correct spot to read engine coolant...

Depends on how much clearance you have between the top of the tank and the bottom of the spigot at the filler neck.

You can't have the outlet and inlet to the rad on the same side using top and bottom tanks, you'll bypass the cooling tubes. If you want to see the proper setup reference a 66 - 67 C-body Imperial with a 413 engine, Which is a RB engine also. If you are not using the OE compressor you will...

I have always been a fan of more cooling capacity than the engine can create. One day after a bit of an overheat, I decided to engineer more available cooling capacity at a reasonable cost. I purchased two Buick heater cores from Rockauto at $34 apiece and two 5" Spal fans for about $22 apiece...

I agree with "silver67" if you don't drive the car in cold climates. Use a dedicated cooler with or without fan to beat those high transmission temperatures in the hot summer.

I do not know who's gauge you bought but Autometer sensors come with an adapter for both 1/4 and 3/8 tap sizes. The extra hole was for future systems requiring a sensor of sorts like the first primitive ECM's , spark control or vacuum heater controls that won't initiate until the engine is warm...

OK don't panic, you just need to look closely at the hole sizes and positions. The rear right is the outlet to the heater which is 1/2 inch, the front right 3/8 is return from the heater. This adds latency for the hot coolant in the heater core. The top left houses another sensor for temperature...

If you have aluminum parts on your engine the best coolant is Ford's newer version of anti-freeze under the Motocraft name. You could also use Chrysler's offering. These coolants are far superior to the brand names because, "guess who's holding the warranty on these vehicles".It is not uncommon...

If what you see on the gauge needle is confirmed to be 185 actually then if the needle moves above that point you're creating more heat. Sometimes a hotter stat can make a car run cooler because of higher temps which "steams" out minute air bubbles in the block and a higher pressure rad cap can...

Because I have electric fans with a very accurate Dakota Digital controller, I use a 160 and let the fans regulate the top temperature I want. Set at 185 (on) and 178 (off) they cycle accordingly. On the highway the temp reads 175 and the fans are off. In the city they come on at 185 and hold...

I run a 512 stroker on a 22" rad and a slight extra cooling fix and my car runs 175 degrees all day, all conditions. I think you'll be OK with a 26" rad, 16 lb rad cap and a 160 stat. I highly recommend you give your existing rad a try before dropping $600 on something you may not need. If your...

Well you can make the same mistakes as many before you and mount one in front of the rad ( so you have warm air blowing on the partially blocked rad), or you can leave your lines connected to the bottom of the rad to make sure your tranny fluid reaches 195 degrees ( don't see the logic in that)...

Isn't it amazing that they have everything in a jar to fix what ails your car. Stuff to stop coolant leaks, condition transmission seals, clean the internals of your engine, decarbonize the upper cylinder chambers, stop noisey lifters, fix leaky rear seals and the list goes on. Hell someone even...

This is gonna blow you away because it's really off the wall. The best flush additives without destroying any internal components is still pedaled by the big car manufacturers. Motocraft Engine Flush and GM's products are totally non destructive as is Chrysler's, clearly labeled for use and...

The pan is the best place to test for temperature unless you have an outboard oil cooling system. The best temperature reading is when the oil has finished circulating through the engine but is still in "flow" state. I would hesitate to use a temperature probe that uses a poly line what with all...

If it's leaking out the hole on the bottom, it's generally the seal. Possibly a defective pump but a replacement "reman" is not all that expensive. Get an 8 vane pump used on a car with A/C or if yours was already just replace it.
